I have a coustomer with an '87 944 with a trashed head (broken
timing belt) and an engine out of an 88 944s with a cracked block
(thrown rod). I was wondering if it was possible to graft the 16v head
onto the 8v block. Or are the watter passages or crank diffrent?

I believe so, but not 100% sure. Doing a search on Rennlist may yield
you an answer.

Good luck!

don't do it. Tell customer to sell the 16V head and buy a rebuilt 8V head -
it MAY work, but the timing belt (hence drive gears) is different, the
computer and wiring on an S is different, the S has a hall effect sensor in
the distributor that is not present in the 8 valve ones - and, if something
goes wrong it's a LOT more expensive to fix. In my experience, broken
timing belt breaks valves, but I haven't seen it actually break the head
itself - why not just do a valve job and put it back?
